Thanks a lot for your help!
Both methods work fine, but it is really more flexible using the package xspace because is not necessary to write always {\gnr} or \gnr\ (any letter), and only adds \xspace after the command. Also, this package respect the dot or comma or similar ie does not add a space then of this.
